We first called this company's main competitor to resurface my cylinder head, they pushed me out a week, I contacted this company next and not only did they take me in today, but called a few hours later saying it was ready THANK YOU!

Up front prices. They are also the quicker of all the other machine shops around with just as good or better workmanship.

Great machine shop. We use them all the time from heads to built motors. Any issues they've always been happy to help and resolve the problem. Great people as well.

They did some machine work on a pair of cylinder heads for me. It was done the next day and the cost was about half of what I was expecting. They are now my go-to machine shop! Service: Engine repair

The team at this machine shop rock! I've been going to them for about 15 years and have never once been disappointed in the service! Just had some cylinder heads in for service and was blown away by how quickly them got them turned around! Price was great as always too. Jeff is a legend, the man knows his stuff. Keep doing the great work team!

I used them to bore and fit new pistons in my 2.9 Ranger block also for cleaning all the misc parts involved. They helped me source parts also. Great work engine runs awesome with excellent oil pressure. We also started using them at the Dealership i work at. 10/10
